ABSTRACT
To conclude these first 10 introductory chapters, three additional applications of correspondence analysis (CA) are now given: (i) a table which summarizes the classification of scientists from 10 research areas into different categories of research funding; (ii) a table of counts of 92 marine species at a number of sampling points on the ocean floor; (iii) a linguistic example, where the letters of the alphabet have been counted in samples of texts by six English authors. In the course of these examples we shall discuss some further issues concerning two-dimensional displays, such as the interpretation of dimensions, the difference between asymmetric and symmetric maps, and the importance of the aspect ratio of the map.
